Amelanchier x grandiflora, or apple serviceberry, is a hybrid species between the Downy serviceberry (Amelanchier arborea) and Smooth serviceberry (Amelanchier laevis), both native trees to Ontario. It prefers medium moisture, well-drained loam soil, and full sun to part shade. It is susceptible to heat and drought, with shallow roots that benefit from mulch to retain moisture and regulate temperature. It is mildly deer-resistant and attracts birds with its fruit. The tree is generally free of major insect and disease issues, though it may occasionally experience powdery mildew and it can be difficult to transplant.
